Inspired by the success of graphene, various two dimensional (2D) structures in free
standing (FS)(hypothetical) form and on different substrates have been proposed recently …

The key scientific issues in the application and development of semiconductor
micro/nanodevices and optoelectronics components have driven scientists to investigate in …

Control of the spin degree of freedom of an electron has brought about a new era in spin-
based applications, particularly spin-based electronics, with the potential to outperform the …

Room temperature ferromagnetism in polycrystalline Co x Ce 1− x O 2− δ (0.001≤ x≤ 0.10)
bulk samples has been investigated. Annealing in the forming gas transformed the as …

Conventional magnetic order in a material requires the partially filled d or f bands. The
exchange interactions between the electrons in these partially filled bands give rise to a …

We investigated the possible formation and segregation of oxygen vacancies near the
surface of SnO 2 thin films from oxygen K-edge x-ray emission and absorption spectra and …

Charged defects are often studied within the periodic density functional theory (DFT), but this
introduces strong finite-size artifacts. In this work, we develop an electrostatic image …

Sn1− x Zn x O2 nanorods with nanoflower morphology have been synthesized by a
solvothermal method. The concentration of Zn dopants is found to play an important role in …

We investigate experimentally and theoretically the origin of magnetism in nanocrystalline-
undoped ceria films. Our results are consistent with density-functional calculations showing …

Sn–O nanoparticles ranging in average particle sizes from 13 to 420 nm have been
prepared by levitation-jet aerosol synthesis through condensation of tin vapor in a mixed …
